Carburetion attachment for auxiliary air

ABSTRACT

A carburetion attachment consisting of a relatively thin insert to be bolted between the carburetor and the intake manifold. The insert has the shape of a normal gasket separating the carburetor from the intake manifold. The insert has openings extending downwardly therethrough coinciding with the throats of the carburetor and the securing bolts therefor. One face of the insert has spiral grooves formed therein with their inner ends opening into the throat opening and their outer ends opening into the peripheral groove in the insert. A felt member is positioned in the peripheral groove to serve as a filter. A plate completely covers the spiral grooves and extends over half of the felt filter in the peripheral groove. The plate seals the spiral grooves to prevent the leakage of air therefrom.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to the drawingsin detail wherein like reference characters indicate like partsthroughout the several figures, the reference 10 indicates generally acarburetion attachment constructed in accordance with the invention.

The attachment 10 includes a generally flat plate 11 having a verticalthroat bore 12 extending downwardly therethrough. Bores 13 for attachingbolts extend vertically through opposite ends of the plate 11.

A relatively deep angular groove 14 opens downwardly into the upper faceof the plate 11 adjacent the peripheral edge thereof. A felt ribbonfilter 15 is positioned in the groove 14 as can be seen in FIGS. 3, 4,

and 5. A plurality of spiral grooves 16 are formed in the upper face ofthe plate 11 with their outer ends communicating with the groove 14 andtheir inner ends communicating with the throat bore 12, as is clearlseen in FIG. 2.

A cover plate 17 engages the upper surface of the plate 11 and seals thegrooves 16 to prevent air leakage therefrom. The outer edge of the coverplate 17 terminates intermediate the opposite sides of the upper face ofthe ribbon felt filter 15 so that air reaching the outer ends of thegrooves 16 must pass through the felt filter 15.

In the use and operation of the invention illustrated in FIGS. 1 to 5,the attachment 10 is bolted between the intake manifold 18 andcarburetor 19 of a conventional internal combustion engine, so thatadditional air may be drawn into the throat bores 12 as engine vacuumapplies force thereto. The spiral construction of the grooves 16 createsacyclone or tornado-like action within the throat of the plate 11 andquick starting with savings in gas use and extra power will be attained.

Referring now to FIGS. 6 through 8, a modified form of the carburetionattachment is indicated generally at 110. The attachment includes arelatively flat plate 111 having a plurality of throat bores 112extending vertically therethrough and having adjacent its four cornersattaching bolt hole bores 113.

An annular groove 114 is formed in the upper surface of the plate 111adjacent the peripheral edge thereof and opening deeply into the plate111. A felt ribbon filter 115 is positioned in the groove 114 forreasons to be assigned. A plurality of grooves 115 is formed in theupper face of the plate 11 with their outer ends communicating with thegrooves 114 and their inner ends communicating with one of the throats112. The grooves 116 open into the throat 112 in a spiral form toproduce the cyclone action described in the operation of the embodimentillustrated in FIGS. 1 through The use and operation of the attachment110 is identical to that of the attachment 10 except that the attachment10 is intended for a one barrel carburetor and the attachment 110 isused with a four. barrel carburetor.

Referring now to FIGS. 9 through 11, another modified carburetionattachment is indicated generally at 210. The carburetion attachment 210includes a generally flat plate 211 having carburetor throat bores 212extending vertically therethrough. Attaching bolt bores 213 openvertically through the plate 211 at the four corners thereof. An annulargroove 214 opens downwardly from the upper face of the plate 211adjacent the peripheral edge thereof for one-half of the distance aroundthe plate 211. A groove 214' opens into the lower face of the plate 211adjacent the peripheral edge thereof and extends from one end of thegroove 214 to the oppositeend of the groove 214, as can be seen in FIG.10. A plurality of grooves 210 are formed in the upper face of the plate211 communicating at their outer ends with the grooves 214 and at theirinner ends with one of the throats 212. A plurality of grooves 216' areformed in the lower face of the plate 211 having their outer endscommunicating with the groove 214' and their inner ends communicatingwith another one of the throats 212. Coverplates 217 and 217' engage theupper and lower faces of the plate 211 to seal the grooves 216, 216'respectively. A ribbon felt filter 215 is positioned in the grooves 214,214' to filter the 1.
